o When we're resetting the board, make sure that we error out the pending
CCBs first. Otherwise the aha_cmd won't accept further commands, such
as those that are used to reset the card (AOP_INITIALIZE_MBOX). This
appears to cause a cascade failure where no more commands are possible
to the card.
o Reduce from 10s down to 1s the amount of time we're willing to tolerate
the card being awol. This helps the above case.
o Add some error checking to two commands issued in the probe.
I have a dim memory of gibbs@ trying to tell me about this problem a
few years ago, so pointy hat to imp@ for sitting on it so long.

Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma. At the moment, this is used for the
asynchronous busdma_swi and callback mechanism. Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg. dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create(). The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.
sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms. The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.
If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

BUS_DMASYNC_ definitions remain as before. The does not change the ABI,
and reverts the API to be a bit more compatible and flexible. This has
survived a full 'make universe'.

Also add commented out pccard lines for all the old card drivers.
They have to be commented out until they are converted because it
causes problems in NEWCARD.

o Cut out the probed stuff. We no longer need it since newbus implicitly
checks for this (likely bt can be changed as well in this way).
o Add preliminary support for unload. Untested because aha doesn't yet
support identify and there are some interactions with PnP that I've
not yet worked out.
With this I can boot the AHA-1542CP FW F.0. All the aha resources
appear to be picked up via pnp now.

resource_list_release. This removes the dependancy on the
layout of ivars.
* Move set_resource, get_resource and delete_resource from
isa_if.m to bus_if.m.
* Simplify driver code by providing wrappers to those methods:
bus_set_resource(dev, type, rid, start, count);
bus_get_resource(dev, type, rid, startp, countp);
bus_get_resource_start(dev, type, rid);
bus_get_resource_count(dev, type, rid);
bus_delete_resource(dev, type, rid);
* Delete isa_get_rsrc and use bus_get_resource_start instead.
* Fix a stupid typo in isa_alloc_resource reported by Takahashi
Yoshihiro <nyan@FreeBSD.org>.
* Print a diagnostic message if we can't assign resources to a PnP
device.
* Change device_print_prettyname() so that it doesn't print
"(no driver assigned)-1" for anonymous devices.

Add debuging for all failure cases in aha_cmd().
Always check DATAIN_REG_READY even if we're ready to exit the
read loop.
The last fix allows the AHA-1640 MCA SCSI adapter to operate
correctly and likely fixes problems on a few other oddball
adapters. (I suspect my Dell Drive Array in 1540 mode needs this.)

work. Be more verbose when one cannot allocate IRQ, et al since this
is a common configuration problem. The cards have the IRQ soft wired
into their BIOS and do not try to do collision detection. This can
cause problems when this IRQ is the same as another card/device.
The PNP hasn't been tested. My PNP board is in a deployed system.
I'll sneak in testing of it sometime later. I've been able to mount
the 3.3R cdrom that arrived today and access files off it.
